//! Output shared by the commands that report findings.
//!
//! `check` and `lint-docs` print the same two things in the same way: a
//! finding line, and the "could not be analyzed" block that carries the exit-2
//! contract. They were transcribed copies, so `lint-docs` inherited a fixed
//! bug by luck rather than by construction: the blank line above the failure
//! block is emitted only when a findings block precedes it, because emitting it
//! unconditionally opened every clean-but-unanalyzed run with a stray empty
//! line.
//!
//! What each command still owns is its own format's shape - `check`'s JSON
//! wire types, `lint-docs`' report-only footer - and the one deliberate
//! difference in the finding line, which is passed as an argument rather than
//! copied.
